How often do you change key fob battery?

[99ron]

Cant tell you whats wrong but fob battteries in mine last about a year before the comfort access starts to play up and I replace it. Did the indie defo register the 95a battery when it was replaced? Assume no related fault codes showing up?

Pretty sure it's all registered
No fault codes on battery as I went back today today to check

After doing some reading it sounds like Comfort Access, keys, increased battery drain has quite a lot of posts on google with faults and issues
